How to Achieve Balanced Urban and Rural Education? 10G All-Optical Education Metropolitan Network Enables Cross-school Dual-teacher Classes

For a long time in the past, education bureaus at county levels and primary and secondary schools generally held the view that connecting campuses to broadband and installing large screens in classrooms meant completing the upgrading of educational digitalization.

In terms of core essential demands such as cross-school synchronous dual-teacher teaching, full-region resource sharing, real-time online classroom inspection and audio-video interactive teaching, relevant applications either operate poorly or cannot be put into use at all. Many regions have long taken poor network conditions in rural areas, interactive video stuttering and isolated educational resources as inevitable long-standing problems.

As the high-quality balanced development of county-level compulsory education and comprehensive implementation of education digitalization projects forge ahead, the development model relying merely on equipment stacking and partial upgrading can no longer keep pace with policy requirements.

The most urgent issue facing county-level education informatization currently lies in how to break down network barriers between urban and rural campuses without redundant investment, large-scale reconstruction and disruption to normal teaching, so as to realize regular operation of cross-school dual-teacher classrooms. Based on practical county-level projects, this paper puts forward a replicable implementation method for all-optical education metropolitan area networks by analyzing existing pain points, construction demands, solution strategies and practical values.

I. Why Are Most County-level Dual-teacher Classrooms Ineffective?

Traditional three-tier network architecture, network cabling and independent broadband access for each school are plagued by severe bandwidth bottlenecks, high network latency, fragmented operation and maintenance, and poor capability to carry audio and video services.

After the nationwide popularization of smart campus upgrading, all hardware facilities are fully equipped, yet numerous persistent problems remain:

4K dual-teacher courses suffer from video stuttering and audio-video desynchronization, and multi-class concurrent teaching easily leads to network disconnection;

Networks of urban and rural schools operate independently with isolated data, making it impossible for education bureaus to uniformly allocate courses and teachers;

Functions such as online classroom inspection, campus visual broadcasting and remote educational administration management fail to work properly.

Consequently, high-quality teaching resources in urban areas cannot be extended to rural regions, weak subjects in rural schools remain underdeveloped, and the urban-rural education gap is hard to narrow down.

Most county-level regions are willing to promote balanced education, but inherent defects of traditional networks hinder the large-scale operation of dual-teacher teaching, synchronous teaching research and remote classroom inspection, which has become a common bottleneck restricting education digitalization across the country.

II. Three Core Dilemmas in County-level Education Digitalization Upgrading

In line with the common renovation demands of campuses nationwide, traditional campus network upgrading is mainly restricted by three key problems that also hinder balanced urban and rural education.

Isolated networks hinder the establishment of dedicated county-level education networks

In the past, schools built independent networks and accessed separate broadband services, resulting in disconnected networks between education bureaus and schools as well as among different schools, forming numerous information silos. Seamless video conferences, unified county-wide course distribution and centralized teaching supervision cannot be realized, limiting education resource circulation within individual regions instead of overall coordinated allocation across the whole county.

Outdated traditional cabling with narrow bandwidth and difficult upgrading

Traditional three-tier network architecture features messy wiring and excessive devices with low bandwidth ceiling, failing to support high-bandwidth applications such as 4K high-definition classrooms, VR virtual experiments and cross-region audio-video linkage. Besides severe line aging, renovation requires full rewiring and computer room reconstruction involving cumbersome construction work that seriously disturbs daily teaching order.

Insufficient audio-video transmission capacity restricts smart scenario implementation

The operation of dual-teacher classrooms, online classroom inspection, campus visual broadcasting and security linkage all rely on stable audio and video transmission. Traditional networks are characterized by high latency, high packet loss rate and slow linkage response, which not only degrade teaching experience, but also impede the implementation of campus visualized management and remote educational supervision.
